It's a series of interconnected dungeon levels sprawling far beneath the city of [[Waterdeep]]. Its tunnels connect to preexisting [[Mithral]] mines and natural caverns of the [[Underdark]]. The best-known entrance to [[Undermountain]] is through the [[Yawning Portal]] tavern in [[Waterdeep]], but other routes also exist. A reclusive and cantankerous [[Archmage]] named [[Halaster Blackcloak]] claims *Undermountain* as his domain, although his overlordship isn't widely acknowledged by the dungeon's other denizens." >
